How to set proceedural mesh collision without baking?

Is it possible to set a UProceeduralMeshCompoent’s collision without baking it? I have tried to use bUseComplexAsSimple = true but it seems like I still need to have the component bake the collision before it works.

I am also using the URuntimeMeshComponent from Koderz, which also has the same issue but allows me to set convex collision directly.

Is it possible to manually specify the collision mesh?
